Edelbrock Single Perf Pontiac Semi Finshed Head

When you're looking to get more out of your Pontiac V8, the Edelbrock #60509 Performer RPM cylinder head is a solid choice. This head is patterned after the well-known Ram Air IV cylinder head from 1969-70, aiming for significant performance improvements in 389-455 cubic inch Pontiac engines built between 1962 and 1979. It features a 72cc combustion chamber, making it suitable for higher compression builds. This particular head comes semi-machined, meaning it's ready for a professional cylinder head porter to complete the final machining to your specific needs. It includes installed valve guides and seats, but note that it does not have intake pushrod holes, which is typical for this style of head preparation.

This Performer RPM head is designed to fit a range of Pontiac engines, and also works with various Buick and Oldsmobile models from the mid-70s, such as the Pontiac Bonneville, Catalina, Firebird, and GTO, as well as the Buick LeSabre and Oldsmobile Delta 88. Because it's semi-finished, it gives you the flexibility to have it precisely ported and finished by a specialist to match your engine's exact requirements, whether you're building a street machine or a more aggressive race setup. The inclusion of installed valve guides and seats means some of the initial setup work is already done, saving you time when you take it to your porter.

It's important to remember that this head requires professional finishing before installation. You'll want to consult with your cylinder head specialist to ensure all final dimensions and porting are done to your desired specifications. This is a bare head, so you will need to source all the necessary valvetrain components, such as valves, springs, retainers, and rocker arms, separately to complete the assembly.
